Key result
Camera-based PPG for remote heart rate monitoring presents advantages and disadvantages versus traditional ECG.
Why the study?
Traditional contact-based methods like ECG are uncomfortable for regular monitoring, driving interest in remote and continuous physiological monitoring techniques.
Camera-based photoplethysmography offers a potential contactless alternative to traditional ECG for continuous heart rate monitoring.
Camera-based photoplethysmography should not yet change practice; leaves open the need for prospective validation against ECG.
Heart rate is one of the major indicators of our physiological state. An irregular or rapid heartbeat, fainting, dizziness, chest pain or shortness of breath can be found by it. The traditional heart rate observing methods such as electrocardiogram (ECG) require physical contact in order to show the heart rate reading exactly but this is uncomfortable for regular monitoring. Techniques for measuring physiological parameters remotely from hospital, as well as monitoring patients continuously, have been one of the major concerns of the scholars. Many heart rate measurement methods using smartphone, webcam, commercial camera etc. have been proposed by many researchers. Image or video processing is the fundamental technique for measuring heart rate through smartphone. With the aim of exploring different heart rate monitoring methods and the advantages and disadvantages, the present study consulted secondary sources like published articles.
